We are working on a project using nrf52832 module and GPRS device. Here we are facing a challenge in updating the firmware to BL652 over GPRS and server.
nrf52832 is connected to serial port of GPRS device and GPRS is directly communicating to our server. We send any data/command from the server to GPRS and it will forward the same data/command to nrf52832 through the serial port.
We have loaded bootloader and application to the nrf52832. Now to upgrade the new application to the device we are using nrfgo studio and nrfutil tools. But in the real scenario, we can't access nrf52832 serial port directly. We can only send data/file to nrf52832 though GPRS device.
How to generate a dfu file so that it should work when i send that file directly to serial port without any nrf tools.
Please guide me on the same.
